We just increased the upload limits here in the video forums.
Now you can upload video files up to 1 GB each. That translates to 1024 Megabytes for you non-techies.

We also allow larger videos to be split into multiple .RAR files up to 1 GB each.
Multi-part .RAR files are okay to post, providing you upload all parts within one day. We don't want you to leave people hanging....
